The article serves as a guide for researchers in developing evidence of validity using bivariate correlations, specifically construct validity. The authors outline the steps for calculating and interpreting bivariate correlations. Additionally, they provide an illustrative example and discuss the implications.

Construct irrelevance (CI) and construct underrepresentation (CU) are 2 major threats to validity, yet they are rarely discussed within the counseling literature. This article provides information about the relevance of these threats to internal validity. An illustrative case example will be provided to assist counselors in understanding these…

The Scylla and Charybdis in this discussion of teacher evaluation are standardized achievement test data on the one hand, and classroom observational systems on the other. These are the two most common methods used to judge teachers' competency. Both have serious flaws: the former primarily with validity, the latter primarily with reliability. At…

The main problem of the educational evaluation validity is that it just copies the conceptual framework system of validity from educational measurement to its own conceptual system. The validity conceptual system that fits the need of theory and practice of educational evaluation has not been established yet. According to the inherent attributive…

Standardizing aspects of assessments has long been recognized as a tactic to help make evaluations of examinees fair. It reduces variation in irrelevant aspects of testing procedures that could advantage some examinees and disadvantage others. However, recent attention to making assessment accessible to a more diverse population of students…

Schilling et al. (this issue) have done a commendable job in illustrating a comprehensive process of validating assessments of teacher knowledge (and, more broadly, other types of tests as well). On one hand, the concrete illustration of a process that often remains murky and incomplete is profoundly heartening, as it provides a rigorous model for…

Teacher knowledge has been of theoretical and empirical interest for over two decades, and development of measures is overdue. The researchers represented in this volume have been breaking new ground by developing a measure of mathematical knowledge for teaching (MKT) without guiding precedents, and in the face of differing perspectives on teacher…

Operating from multiple literature bases in cognitive psychology, mathematics education, and theoretical and applied psychometrics, Schilling, Hill and their colleagues provide a systemic approach to studying the validity of scores of mathematical knowledge for teaching. This system encompasses an array of task formats and methodologies. The…

Indicators of mathematics and science education progress are important to policymakers and the public in order to evaluate the quality of education. Recent reports have evaluated existing indicators and suggested core aspects of mathematics and science education that an indicator system should evaluate. This note discusses two fundamental aspects…
